Answer:
Every option is correct except option C.
Option A is the most accurate statement of the law
Explanation:
C is incorrect because momentum of the SYSTEM is conserved and not necessarily that of the individual objects in the System.
For option B, momentum is a vector quantity but it does not describe the principal of conservation of momentum. Option D is also correct but does not state anything about the conservation of momentum.
The East African rift is an example of a divergent tectonic plate boundary that is developing. Though it is still currently a narrow zone, it is currently experiencing the process of splitting into two different tectonic plates. Over time, the supposed narrow zone can split into a larger one.
Answer:
a 15.22 m/s
b 45.65 m
Explanation:
Using the same formula,
x = vt, where
x is now 45.65, and
t is 3 s, then
45.65 = 3v
v = 45.65/3
v = 15.22 m/s
See the attachment for the part b. We used the distance gotten in part B, to find question A
Answer:
I believe it is A. The human body would not function normally without essential body fat.
Explanation:
Answer:
14.1 kg
Explanation:
Given:
Length=7.00inches
Width=3.63 inches
Height=1.75 inches
density = 19,300 kg/m3.
We can convert the given parameters to metre for unit consistency
But we know 1 inches= 0.0254 metre
✓Then Length l=7.00inches
=7×0.0254 metre=0.1778m
✓Width w =3.63 inches
==3.63 ×0.0254 metre=0.092m
✓Height h =1.75 inches
=1.75 ×0.0254 metre=0.0445 m
But Mass= density × volume
Volume= Length× width×height
Mass= density× Length× width×height
= 19300kg/m³×0.1778×0.0922×0.0445
=14.1 kg
Therefore, the mass of the gold bar is 14.1 kg
